Call To Action:
fn_generate_random.js returns a number (x), an operator (+, -, multiply, /divide/), and another number (y).
Within the /divide/ operator, I check if it is a positive whole number (using regex ^[1-9][0-9]*$), make sure you don't divide by 1, and then make sure you aren't dividing by itself.
Within the main flow, there is a bit of a delay on the phone because it has to generate the number and test all these conditions until it finds one that randomly works.
Do you think it'd be easier to add the math criteria into the javascript file? Or should I just play a little music for the 2-5 seconds it takes to calculate so the user doesn't worry that something is wrong.
